Questions I have been a Christian my whole life, but I am just now beginning to read the Bible. I have only gotten to about chapter 20 and I already have so many questions. First of all, why did people live to be so old in the Bible? Isn't that genetically impossible? Second, how did Cain get his wife? And thirdly, how did Noah's family reproduce after the flood? Wouldn't that be incest? And seeing as they were all closely related, how did they manage to escape retardation? Any help would be appreciated. Thanks.
